Embodiment 1

[0018] Example 1: Rhizoma Rhizoma Rhizoma Polygonatum Planting Base under the pine forest of Zhenyuan Guihuajia Biological Industry Co., Ltd., Pu'er City, Yunnan Province

[0019] Planting and management in 2015:

[0020] In the artificial pine forest with a tree age of more than 6 years, in the early February of 2015, the rhizome seedlings of Polygonatum rhizomes were planted under the aforementioned pine forest as usual, and the branches of the pine forest were pruned in time to maintain the forest light transmittance during the growth of Polygonatum at 25. % to 30%, in the late October of the planting year, when 8% of the plant population of the above-ground part of Polygonatum yunnanensis is withered and yellow, all the stems and leaves of the above-ground part of Polygonatum yunnanensis are cut off.

[0021] According to the conventional description, rhizome seedlings of Polygonatum rhizomes are selected to be 3 to 4 years old, with full terminal buds, no damage by diseas...

Embodiment 2

[0029] Example 2: Rhizoma Polygonatum Planted in the Walnut Grove at Zhenyuan Guihuajia Biological Industry Co., Ltd., Pu'er City, Yunnan Province

[0030] Embodiment 2 In addition to planting rhizome seedlings of Rhizoma Polygonatum under the artificial walnut forest over 6 years old and 2015-2017 in late October each year, when 12% of the plant populations of the above-ground part of Polygonatum Diannian are withered and yellow, all the stems of Rhizoma Polygonatum Diannian in the above-ground part are cut off Outside the leaf, all the other measures are identical with embodiment 1.

Abstract

The invention relates to a lodging-resistant method for planting polygonatum kingianum under the forest, belonging to the technical field of medicinal plant cultivation. Key technologies are as below:pruning branches in time to maintain forest transmittance around 25%-30%; and every year in late October, when 8%-12% of the polygonatum kingianum plants above ground are withered, cutting away all stems and leaves of the polygonatum kingianum plants above ground to prevent nutrient consumption of the stems and leaves in advance, and to promote the overwintering buds to grow robustly below ground. The method provided by the invention is easy to conduct, and has low cost; the grown-up plants each year are strong, and lodging-resistant; and the lodging rate drops down significantly, ensuring the yield of the polygonatum kingianum.

Description

technical field [0001] The invention relates to a lodging-resistant method for planting Polygonatum yunnanensis under forests, and belongs to the technical field of medicinal plant cultivation. [0002] technical background [0003] Rhizoma Polygonatum is a perennial herb of the genus Polygonatum in the family Liliaceae. Its rhizome is used for medicine. It is the 3 kinds of native plants used as Polygonatum medicinal materials in the 2015 edition of "Pharmacopoeia of the People's Republic of China", namely Polygonatum kingianum Coll. et Hemsl, Polygonatum sibiricum (Polygonatum sibiricum Red.) and Polygonatum cyrtonema Hua (Polygonatumcyrtonema Hua), is a traditional bulk medicinal material used both in medicine and food in my country. It is an authentic medicinal material variety in Yunnan Province, mainly produced in Yunnan. Sichuan, Guizhou, Guangxi and other provinces and regions also have a certain distribution, mainly growing in shady forests and shrubs at an altitude o...
